Tank dividers

[johnchor]

hello folks

i am planning to divide my 4ft into 4 sections.
i know most of the guys here use acrylic but the problem is acrylic is expensive.
where to get cheap acrylic?

also i saw some professional dividers make for fish tanks on internet. just wonder if anybody use or see them before?

holders you can get from Mainland Tropical Fish Farm or OTF, though it may not be as similar to the pictures you have provided.
Acrylic you can get from Art friend but you have to cut by yourself. HTH
